You have to install one image or the other. You can't install both. There are instructions on the Raspberry Pi webpage on how to install an image:

I'm going to share some information that will help you with etiquette on forum posts. I'm glad that you're interested in the Pi and that you're trying something new. Please keep asking questions and learning. I like that about you. I hope you do something wonderful with the Pi. I hope that you know that I'm telling you this information to help you better participate on online forums.
I'm not yelling or angry, but I think you need to know that it is rude to ask "plz help and make instructions". 1) If you're going to ask for help, please use full words and sentences. If you want me to spend my time helping you, please use an extra two seconds to spell out the word and show respect. I understand that it is normal to write like this to your friends, but it is not the same when you are first contacting strangers on the internet 2) When you say "plz help" you're implying that your need is greater than anyone else's on the forum. You really don't ever have to use "plz help" in a post, because asking a question is asking for help. If you do want to include it, please say something like "Can you please help me, I'm having problems understanding how to...".
Telling us to "make instructions" means you're ordering us to spend a lot of time doing something. That's not a question or a request. It's a demand. I don't know you and if you tell me to do something, I'm not very likely to want to help you. A more constructive way of saying this is, "I'm a new user and I'm a little confused by the process. Do you know of any detailed instructions?" and then "I still don't understand. Would you be able to help me with more detailed instructions?". If I didn't already know that there was a URL with the instructions, I wouldn't have posted this.
